# Create global symbol declarations, transfer vector, and
# linker options files for PerlShr.
#
+# Processes the output of makedef.pl.
+#
# Input:
-# $cflags - command line qualifiers passed to cc when preprocesing perl.h
-# Note: A rather simple-minded attempt is made to restore quotes to
-# a /Define clause - use with care.
+# $cc_cmd - compiler command
# $objsuffix - file type (including '.') used for object files.
+# $libperl - Perl object library.
+# $extnames - package names for static extensions (used to generate
+# linker options file entries for boot functions)
+# $rtlopt - name of options file specifying RTLs to which PerlShr.Exe
+# must be linked
#
# Output:
-# PerlShr_Attr.Opt - linker options file which speficies that global vars
+# PerlShr_Attr.Opt - linker options file which specifies that global vars
# be placed in NOSHR,WRT psects. Use when linking any object files
# against PerlShr.Exe, since cc places global vars in SHR,WRT psects
# by default.
-# PerlShr_Sym.Opt - declares universal symbols for PerlShr.Exe
+# PerlShr_Bld.Opt - declares universal symbols for PerlShr.Exe
# Perlshr_Gbl*.Mar, Perlshr_Gbl*.Obj (VAX only) - declares global symbols
# for global vars (done here because gcc can't globaldef) and creates
# transfer vectors for routines on a VAX.
# library has everything old one did
# (i.e. /Define=DEBUGGING,EMBED,MULTIPLICITY)?
